'AXLE-LUBlRICATOR.

SPECIFICATION forming part of Letters Patent No. 272,398, dated February13, 1883.

Application filed December 27,1882. (ModeL) contrived to retain thelubricant longer than in the common arrangement, the said deviceconsisting essentially of a tube located in an axial hole of theaxle-tree, with contrivances for opening and closing the outer end ofthe tube for supplying the oil .and securing it therein, together withother contrivances to facilitate the use of the said improved lubricating device, all as hereinafter fully described.

' in g-tube.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of a carriage-axleprovided with our im-' packing employed to prevent the escape of oil outof the nut by'which the wagon-wheel is secured on the axle.- Fig. 6 is aside view ofthe axle with our improved lubricating device applied to it,and Fig. 7 is a side elevation of the screw-cap employed to close thelubricat- We make an axial hole in the axle a, from the outer end aboutas deep as to the shoul der b, and of suitable size to receive alubricating-tube, c, of approved size for the capacity required, and fitsuch a tube therein to reccive and hold the lubricating material, withor without absorbent material, and to supply the lubricant through abranch tube, (1, to the axle-box through a slot, 0, extending from thebore of theaxle throughthelower'sideof'the" axle, where theaxle-box hasa groove, f, extending along it to allow the lubricant to flow along'thebox. The branch tube 01 is made to extend entirely across the tube c-andscrew into the opposite side for a more substantial connection of saidbranch tube d, which has small holes g through itssides'to admit thelubricant to the absorbent material packed in said tube. The inner endof the lubricatingtube is closed with a plug, h, and the outer end isclosed with a plug, 6, which plugs are to be removed from time to timewhen it may be required to wipe out the tube and clean it of any mattersdepositingin it.

tube, which does not extend to the inner end of the bore of the axle,there is a coiled spring, j, that is employed for thrusting the otherend of the tube out of the axle a little for convenience of pouring inthe oil when the cap It is removed, the object being to project saidtube the washer m, which forms the'ornamental tip of the not it employedto secure the wheel on the axle. The cap it has a packing-ring orwasher, 0, let in a groove in the face, to be drawn tightly against theend of washer m by the hollow screw-threaded sleeve 19, projecting fromthe inner face of caplc and screwing into said washer m. the inner endagainst the washer q and collar 8 of the lubricating tube, which packthe washer t tightly against the outer end of the axle, so that thelubricant cannot escape from either end of the tube along it and wasteat the joint of nut n with the end of the axle. The screw-threadedsleeve 10 of the cap 7c has a hole, a, through which the oil or otherlubricating material is to be poured, for filling the tube 0 when thecap his screwed back sufficiently and set so that its hole a coincideswith hole Zin the tube, the latter being pushed out by the springjbeyond the end of washer m.

To facilitate the adjustment and renewal of the packing was'her itwithout taking out the tube 0, we prefer to make said tube 0 in twosections, which connect by a tight screw-joint, 10, between collar 8 andthe tube d. The slot 0 for the tube (1 allows tube 0 to shift forwardand backward, asabove described, for filling.

We also make a circumferential groove, as, in the surface of the axle atthe place where the Back of the inner end of the lubricating' far enoughto extend the filling-hole 1 beyond' This sleeve 19 packs atlubricantissues from tube cl to facilitate the circulation of the lubricant.

The cap it is provided with a milled flange, y, to facilitate theturning of it.

It will be seen that the tube can be filled at any time without takingoff the wheel; also that the wheel may be taken olf at any time whenrequired without taking out the tube, and that the tube will receive aquantity of lubricating material sufficient for a considerable length oftime, and will utilize it grad ually and without waste, especially ifthetubes 0 and (I be packed with absorbent material.

The tube 0 may of course be made in asingle piece, dispensing with thescrew-joint 10, if desired.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the lubricating-tubes c and d with the axle (1,having the central bore and the lateral passage 0, the said tube 0 beingadapted to be supplied with the lubricating material, substantially asdescribed.

2. The combination of the tubes 0 and d, springj, and cap it with theaxle at, having the central bore and the lateral passage 0,substantially as described.

3. The combination of the tubes 0 and d, spring j, cap k, screw-threadedsleeve 1;, packing-collar s,and washers q and t with the axle Masts thenut a, cap 70, sleeve 19, lubricating-tubes c and (1, and the axle at,having the central bore and the lateral passage 0, substantially asdescribed.

5. The tube 0. having packing-collar s, and tube 02, and being made intwo sections joining together at 20, between said collar s and tube d,in combination with hollow axle a and the cap k, having screw-sleeve1;,substantially as described.

6. The tube 0, having removable end plugs, h and i, and being arrangedin the hollow axle a, substantially as described.

7. The combination of cap 70, screw-sleeve p, and packing-washer o withthe washer m, lubricating-tubes c and d, and the hollow and slotted axlea, substantially as described.

8. The combination, with axle a, centrally bored and fitted with pluggedand packed tube 0, having a connection, d, of the orifice e, andconnecting peripheral and longitudinal distributing-grooves m f,substantially 'as shown and described.
